On the specific topic of film, there is the Francois Truffaut auteur theory, which suggests that in order for a film to be recognized as art, there must be one guiding hand on the entire project. This is to say that the auteur must be all things to the film – He or she must write the screenplay, cast the actors, direct and edit the film in order for it to be considered a work of art. Truffaut allows that others may set the lights, operate the cameras and fill other duties but all creative decisions must be solely and strictly that of the filmmaker.
The question is how does this definitioin fit in animation where the vast majority of films are made with a team of artists and technicians working together, often independently?
